GENERAL DESCRIPTION
The AD7623 is a 16-bit, 1.33 MSPS, charge redistribution SAR,
fully differential analog-to-digital converter (ADC) that
operates from a single 2.5 V power supply. It contains a high
speed 16-bit sampling ADC, an internal conversion clock, an
internal reference (and buffer), error correction circuits, and
both serial and parallel system interface ports. Power consump-
tion is automatically scaled with throughput, making it ideal
for battery-powered applications. It is available in 48-lead, low
profile quad flat package (LQFP) and a lead frame chip-scale
(LFCSP_VQ) package. Operation is specified from
40°C to +85°C.
PRODUCT HIGHLIGHTS
1.
Fast Throughput.
The AD7623 is a 1.33 MSPS, charge redistribution,
16-bit SAR ADC.
2.
Superior Linearity.
The AD7623 has no missing 16-bit code.
3.
Internal Reference.
The AD7623 has a 2.048 V internal reference with a
typical drift of ±7 ppm/°C.
4.
Single-Supply Operation.
The AD7623 operates from a 2.5 V single supply and
typically dissipates 45 mW. Its power dissipation decreases
with the throughput.
5.
Serial or Parallel Interface.
Versatile parallel (16- or 8-bit bus) or 2-wire serial interface
arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.
